  2. Elimination reaction - Wikipedia

    en.wikipedia.org/wiki/Elimination_reaction

    E1 is a model to explain a particular type of chemical elimination reaction. E1 stands for unimolecular elimination and has the following specifications It is a two-step process of elimination: ionization and deprotonation. Ionization: the carbon-halogen bond breaks to give a carbocation intermediate. deprotonation of the carbocation.

  3. E1cB-elimination reaction - Wikipedia

    en.wikipedia.org/wiki/E1cB-elimination_reaction

    An example of the E1cB reaction mechanism in the degradation of a hemiketal under basic conditions. The E1cB elimination reaction is a type of elimination reaction which occurs under basic conditions, where the hydrogen to be removed is relatively acidic, while the leaving group (such as -OH or -OR) is a relatively poor one.

  4. Porphobilinogen deaminase - Wikipedia

    en.wikipedia.org/wiki/Porphobilinogen_deaminase

    Full PBG Deaminase Mechanism. The first step is believed to involve an E1 elimination of ammonia from porphobilinogen, generating a carbocation intermediate (1). [10] This intermediate is then attacked by the dipyrrole cofactor of porphobilinogen deaminase, which after losing a proton yields a trimer covalently bound to the enzyme (2).

  5. Arrow pushing - Wikipedia

    en.wikipedia.org/wiki/Arrow_pushing

    An E1 elimination occurs when a proton adjacent to a positive charge leaves and generates a double bond. Because initial formation of a cation is necessary for E1 reactions to occur, E1 reactions are often observed as side reactions to S N 1 mechanisms. E1 eliminations proceed with the Elimination of a leaving group leading to the E designation ...

  6. Fumarase - Wikipedia

    en.wikipedia.org/wiki/Fumarase

    This led to the conclusion that the formation of S-malate proceeds as E1 elimination - protonation of fumarate to create a carbocation was followed by the addition of a hydroxyl group from H 2 O. However, more recent trials have provided evidence that the mechanism actually takes place through an acid-base catalyzed elimination by means of a ...

  9. Evelyn effect - Wikipedia

    en.wikipedia.org/wiki/Evelyn_effect

    There are two types of elimination reactions, E1 and E2. An E2 reaction is a One step mechanism in which carbon-hydrogen and carbon-halogen bonds break to form a double bond. C=C Pi bond. An E1 reaction is the Ionization of the carbon-halogen bond breaking to give a carbocation intermediate, then the Deprotonation of the carbocation.
